Abstract:
... 1. Senescing, shade-suppressed, or broken branches of Monterey pine Pinus radiata are infested by twig beetles in the genus Pityophthorus (Coleoptera: Scolytidae). The studies reported here tested whether twig beetles can discriminate between healthy and pitch canker-diseased branches, whether diseased branch tips produce more ethylene than undamaged controls, and whether ethylene and other volati ...

Xylem tissues beneath the cankers were resinsoaked as is characteristic of pitch canker on other southern pine species. Surface-sterilized stem pieces from the canker margins were transferred to acidified potato dextrose agar and incubated ...

Abstract:
... The plant pathogenic fungus, Fusarium circinatum, is the cause of a major epidemic of pitch canker in urban forests of Monterey pine (Pinus radiata) in California. This pathogen is now also well established in all three mainland, native populations of Monterey pine where it causes conspicuous branch die-back and, frequently in association with native bark beetles, increased tree mortality. In the ...

The pitch canker fungus, Fusarium circinatum (teleomorph Gibberella circinata), was isolated from a branch originating from rootstock of a Douglas-fir (Pseudotsuga menziesii) graft in a breeding orchard at 1,000m elevation in El Dorado County, California. We visited the orchard after the New Zealand Ministry of Agriculture and Forestry reported in November 2003 that a Douglas-fir scion (branch cut ...

Abstract:
... Pitch canker, caused by Fusarium circinatum, is a disease affecting pines in many locations throughout the world. The pathosystem was originally described in the southeastern (SE) United States and was identified in California in 1986. Limited vegetative compatibility group (VCG) diversity in the California population of F. circinatum, relative to the SE United States, suggests the former is a rec ...

Patterns of spore deposition by Fusarium circinatum, the causal agent of pine pitch canker (PPC) of Monterey pine (Pinus radiata) and other conifers, were studied between May 2003 and April 2004 at two sites in Northern California using a novel spore trapping method combined with a real-time polymerase chain reaction (PCR) approach. At each study site, two plots were sampled by placing spore traps ...

Abstract:
... Pitch canker, caused by Gibberella circinata, was discovered in California in 1986. Although initially quite damaging to Monterey pines (Pinus radiata), the severity of pitch canker has moderated in areas where the disease was first observed and some trees appear to have recovered completely. The absence of symptoms on trees that were once severely affected implies they have become more resistant ...

Abstract:
... Gibberella circinata (anamorph Fusarium circinatum) causes pitch canker in pines and is not known to have any hosts outside the Pinaceae. However, G. circinata is closely related to and interfertile with G. subglutinans, which is associated with grasses both as a pathogen and a commensal endophyte. Furthermore, studies under controlled conditions have shown that G. circinata can colonize corn (Zea ...

Abstract:
... The pitch canker pathogen, Fusarium circinatum , has major impacts on production in pine nurseries and plantations in South Africa. Thus far, efforts to reduce local spread have focused on rouging of infected pines and sanitation to eliminate local sources of inoculum. Although the host range of F. circinatum was thought to be limited to pines and Douglas-fir, recent studies in California indicate ...

SUMMARY: Fusarium circinatum is widely regarded as a necrotrophic pathogen of pines that infects shoot tissue through mechanical or insect‐mediated wounds, causing girdling lesions that result in death of infected branches. However, in the study reported here, F. circinatum colonized 100% of seedling stems and 70% of mature tree branches that were not wounded. Hyphae were observed beneath the epid ...
